Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, of the present utility model had integrated import knock out drum and comprise along natural gas flow to the rock gas suction port 1 be connected by pipeline successively with the natural gas compressor of recycling can, integrated import knock out drum and recycling can 2, at least two-stage natural gas compressing cooling unit and rock gas relief opening 3, wherein, rock gas suction port 1 is connected with the first suction port 4 of integrated import knock out drum and recycling can 2 by the first pipeline L, the air outlet of integrated import knock out drum and recycling can 2 is connected with at least two-stage natural gas compressing cooling unit by the second pipeline M, at least two-stage natural gas compressing cooling unit is connected with rock gas relief opening 3 by the 3rd pipeline N.Every grade of natural gas compressing cooling unit is comprised along natural gas flow to the filter connected by the second pipeline M successively, cylinder and cooler.In a preferred embodiment, natural gas compressor of the present utility model comprises level Four natural gas compressing cooling unit, first order natural gas compressing cooling unit comprises the first filter 5, first cylinder 6 and the first cooler 7, and fourth stage natural gas compressing cooling unit i.e. final stage natural gas compressing cooling unit comprise final stage cylinder 8 and aftercooler 9.Before integrated import knock out drum and recycling can 2 are arranged on first order natural gas compressing cooling unit, when rock gas flows through integrated import knock out drum and recycling can 2 by Imported gas 1, just play the effect to gas buffer.
Second suction port 17 of integrated import knock out drum and recycling can 2 is by being connected with the pipeline of the outlet side of final stage cylinder 8 with the 4th pipeline P of the second pipeline M parallel connection.In a preferred embodiment, on the first pipeline L along natural gas flow to being disposed with the first manual ball valve 11, second manual ball valve 12, first pneumatic ball valve 13 and the first one-way valve 18.The pipeline of integrated import knock out drum and the air outlet of recycling can 2 is provided with the second pneumatic ball valve 14.Along natural gas flow to being disposed with the 3rd pneumatic ball valve 15 and the second one-way valve 16 on 4th pipeline P.The pipeline of the inlet end of aftercooler 9 is provided with the 3rd one-way valve 10, can the effective quality of rock gas that reclaims of power generating ratio.First cylinder 6 is provided with bypass valve, gets bypass action when shutdown is restarted, and then reduces starting load, and in a preferred embodiment, bypass valve is the 4th pneumatic ball valve 19.
After compressor reaches default shutdown pressure, compressor remains in operation, and PLC controls compressor circuit, and now the working method with the natural gas compressor of integrated import knock out drum and recycling can of the present utility model comprises the following steps:
(1) cut off the first pneumatic ball valve 13, stop rock gas to continue to flow to compressor from rock gas suction port;
(2) cut off the 3rd pneumatic ball valve 15, stop natural gas via the 4th pipeline P in compressor circuit to be recovered to integrated import knock out drum and recycling can 2;
(3) the second pneumatic ball valve 14 is opened, compressor maintains and runs, the rock gas taken away in integrated import knock out drum and recycling can 2 continues compression air feed, when pressure in integrated import knock out drum and recycling can 2 be shown as subtract Xpsi lower than the minimum inlet pressure of pipeline time (numerical value X calculates gained according to actual conditions), compressor is formally shut down;
(4) cut off the second pneumatic ball valve 14, stop the rock gas in integrated import knock out drum and recycling can 2 to continue to flow to compressor.
(5) open the 3rd pneumatic ball valve 15, integrated import knock out drum and recycling can 2 reclaim the remaining rock gas in compressor circuit, and now integrated import knock out drum and recycling can 2 play the effect of reclaiming rock gas.
As described in step (3); because the most of rock gas in integrated import knock out drum and recycling can 2 is found time in advance; and the rock gas in conduit assembly (comprising cooler, filter etc.) after final stage cylinder 8 is not unloaded and is put back in import knock out drum and recycling can 2; so when after the rock gas in compressor shutdown reclaim line; total gas pressure in import knock out drum and recycling can 2 is not high, ensure that the little volume design of the low-pressure of this container.
Integrated import knock out drum of the present utility model and recycling can 2 integrate import knock out drum and recycling can, the effect that the rock gas flowed into is cushioned can either be played, play again the effect of the remaining rock gas reclaimed in compressor circuit, thus client will without the need to buying import knock out drum more in addition, thus realize import knock out drum and recycling can and share, reduce container volume and design pressure, reduce costs.
The above embodiment only have expressed mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
